In this activity the child sits with a beanbag on the head and lifts a large bottle filled with water above the head 10 times. The amount of water in the bottle is adjusted so that the child can lift the bottle just 10 times with ease.
This activity strengthens the neck, trunk and shoulder muscles. The beanbag on the head means that the child has to lift the bottle slowly and carefully. The beanbag on the head also means that the neck muscles have to work harder to keep the head steady.
